QUESTION 1 of 10

Letter detective, we need your help! In this activity, we will be using the alphabet to help us crack a letter code!

Here is the alphabet for you to use as a reference:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Now look at the following letter sequence:

AD is to DG as GJ is to ___.

?First, we have to work out how the first letter of the first pair A(AD) gets to the first letter of the second pair to the letter D(DG).

To get from A to D, we jump 3 places to the right.

Then we have to work out how the second letter of the first pair gets to the second letter of the second pair.

To get from D to G, we also jump 3 places to the right.

This means we need to do the same to the letters G and J to work out the missing letters in our sequence.

This means our missing pair of letters is JM.

So the answer is:

AD is to DG as GJ is to JM.

Let’s try another:

DF is to HJ as PR is to ___.

First, we have to work out how the first letter of the first pair (DF) gets to the first letter of the second pair (HJ).

To get from D to H, we jump 4 places to the right.

Then we have to work out how the second letter of the first pair gets to the second letter of the second pair.

To get from F to J, we also jump 4 places to the right.

This means we need to do the same to the letters P and R to work out the missing letters in our sequence.

This makes our missing letters TV.

In this activity, you will need to be a sequence superstar and complete the letter pairs.

Pssstt!! Here’s a handy hint to help you reach superstar status:

Remember to use the alphabet line to help you work out the code.

ANSWERS

Question 1

Here are two letter sequences that both follow the same pattern:

AB is to CD as GH is to ______ ?

You may use the alphabet chart below to help you:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

CORRECT ANSWER

IJ

EDDIE SAYS

Each sequence has letter pairs and the sequence is one jump going forwards in the alphabet. When working out the sequence you look at the last letter of the first letter pair and work out the number of jumps to the first letter of the next letter pair. So one jump from GH is IJ. Great!

ANSWERS

Question 2

Here are two letter sequences that both follow the same pattern:

EF is to IJ as RS is to ______ ?

You may use the alphabet chart below to help you:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

CORRECT ANSWER

VW

EDDIE SAYS

How did you get on? Each sequence follows the order of the alphabet going forwards, with three jumps each time. So three jumps after RS is VW.

ANSWERS

Question 3

Here are two letter sequences that both follow the same pattern:

MN is to XY as GH is to ______ ?

You may use the alphabet chart below to help you:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

CORRECT ANSWER

RS

EDDIE SAYS

Getting the hang of it? Both sequences follows the order of the alphabet going forwards, with ten jumps each time. So ten jumps from GH is RS.

ANSWERS

Question 4

Here are two letter sequences that both follow the same pattern:

VW is to AB as IJ is to ______ ?

You may use the alphabet chart below to help you:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

CORRECT ANSWER

NO

EDDIE SAYS

Fantastic effort! Both sequences follow the order of the alphabet going forwards, with four jumps each time. Four jumps from IJ is NO.
Remember that you start back at the beginning of the alphabet when following a forwards sequences that has reached the end of the alphabet.

ANSWERS

Question 5

Here are two letter sequences that both follow the same pattern:

WX is to GH as UV is to ______ ?

You may use the alphabet chart below to help you:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

CORRECT ANSWER

EF

EDDIE SAYS

Both sequences follow the order of the alphabet going forwards, with nine jumps each time. Nine jumps from UV is EF. Good work detective, you're already halfway through this activity!

ANSWERS

Question 6

Here are two letter sequences that both follow the same pattern:

DC is to BA as HG is to ______ ?

You may use the alphabet chart below to help you:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

CORRECT ANSWER

FE

EDDIE SAYS

Did you work this one out? This time both sequences go backwards in the alphabet. There is one jump each time. So one jump back from HG is FE.

ANSWERS

Question 7

Here are two letter sequences that both follow the same pattern:

MN is to YZ as PQ is to ______ ?

You may use the alphabet chart below to help you:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

CORRECT ANSWER

BC

EDDIE SAYS

Both sequences follow the order of the alphabet going forwards, with eleven jumps each time. So eleven jumps from PQ is BC. Super!

ANSWERS

Question 8

Here are two letter sequences that both follow the same pattern:

NM is to KJ as RQ is to ______ ?

You may use the alphabet chart below to help you:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

CORRECT ANSWER

ON

EDDIE SAYS

Both sequences follow the order of the alphabet going backwards, with two jumps each time. So two jumps back from RQ is ON. Good work, detective!

ANSWERS

Question 9

Here are two letter sequences that both follow the same pattern:

WV is to QP as LK is to ______ ?

You may use the alphabet chart below to help you:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

CORRECT ANSWER

FE

EDDIE SAYS

This sequence follows the order of the alphabet going backwards, with five jumps each time. So five jumps back from LK is FE.
Let's zoom onto the final question!

ANSWERS

Question 10

Here are two letter sequences that both follow the same pattern:

OP is to CD as TU is to ______ ?

CORRECT ANSWER

HI

EDDIE SAYS

Both sequences follow the order of the alphabet going forwards, with thirteen jumps each time. So thirteen jumps from TU is HI.
What could be better? You've located all the letters! Hooray!
